Photoshop hoc, ergo hoc vera is a logical fallacy whereby something is assumed to be true because someone photoshopped a picture of it.
An example of "Photoshop hoc, ergo hoc vera" is a picture of a Nobel Prize stained in blood stating that someone doesn't deserve a Nobel Prize because they are responsible for more deaths than Hitler. "Photoshop hoc, ergo hoc vera" applies people assume that the picture is true just because someone made it, and then share it with others.
